Switch Case Statement

Lesson 6 of 11 in Coddy's Control Statements in Java course.

If-else-if statements are similar to switch statements.

The switch statement contains multiple blocks of code called cases, and a single case is executed based on the variable that is being switched.

There are several possible execution paths.

There can be N number of cases.

Every case should be unique.

For example, you want to know which month it is by entering the input as a month number, so the Switch statement can be used.

Each case statement can have a break as an optional feature.

Syntax:

switch(expression){     
	case value1:    
		//code to be executed;    
		break;  //optional  
	case value2:    
		//code to be executed;    
		break;  //optional  
	......    
	default:     
		// code to be executed if all cases are not matched;  
}

Challenge

Easy

Write a switch case program to implement Days of the Week.

Take int as input, and the week starts on Monday, so print the day accordingly.

Example: if input is 4, then it should print "Thursday".

The default case is "Invalid"

Try it yourself

class DayOfWeek {
    public static String dayOfWeek(int day) {
        // Write code here
    }
}
